Answer:Three general classes of RNA molecules are involved in expressing the genes encoded within a cell's DNA. Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein synthesis. In eukaryotic cells, each class of RNA has its own polymerase, whereas in prokaryotic cells, a single RNA polymerase synthesizes the different class of RNA. Other types of RNA also exist but are not as well understood, although they appear to play regulatory roles in gene expression and also be involved in protection against invading viruses.

Which sentence correctly explains the process and conditions needed for hail to form? (worth 30 points)
Group of answer choices
A. The temperature of the air and the temperature of the cloud must be below zero.
B. Liquid water requires temperatures above 0 °C in order to remain in a liquid state.
C. A form of precipitation requires melting and refreezing as they fall towards the ground.
D. Ice chunks move around inside a cloud, bouncing into water droplets and growing as they fall.

Explanation:
What supports, protects and maintains the shape of the cell? *Very rigid. *
A .golgi apparatus
B. cytoplasm
C. endoplasmic reticulum
D. cell wall
Answer: D. the Cell wall
Explanation: The cell wall provides structural support and protection. Pores in the cell wall allow water and nutrients to move into and out of the cell. The cell wall also prevents the plant cell from bursting when water enters the cell.
Also it is also a ridged layer found outside of the cell membrane

A plant has been removed from its natural environment and placed into a body of water that contains a higher concentration of salt than the inside of each plant cell. The plant promptly wilts. This situation is most similar to which event?
a. Seaweed put into fresh water.
b. A land plant put into tap water.
c. A freshwater plant put into sea water.
d. A freshwater plant put into distilled water.
Answer:
Explanation:The situation that is most similar in which a plant is moved to a higher concentration of salt in water is that of a freshwater plant being put into sea water. Due to too much salt concentration, freshwater plants cannot survive on the ocean
why is deforestation a threat to Yellowstone National Park?
Answer:
Deforestation causes loss of animal and plant species due to their lack of habitat. A huge portion of animals and plant species live in forests so if we take that away from them how are they supposed to survive? Not only does deforestation threaten species known to us, but also threatens species we haven't even discovered yet.
Explanation:
This isn't necessarily for Yellowstone but for all national parks ^

The monohybrid phenotype identifies
A) what it eats
B) where it is found
C) genes of offspring
D) how it looks
Answer:
C) genes of offspring
Explanation:
A monohybrid cross is a genetic cross between two individuals who have different genetic variation at one gene, resulting in different traits. For example, a cross between a plant with white flowers and a plant with purple flowers.
The phenotype of the offspring gives details about which trait is dominant and which trait is recessive.

Refer to the family pedigree shown here. In generation I, one parent is affected by the gene mutation and one parent isn't. In generation II, all three children are affected by the gene mutation. What can you conclude about this gene mutation?
Answer:
What can be concluded about this genetic mutation is that it is inherited as a dominant trait.
Explanation:
In the case that one of the parents has a mutation whose inheritance pattern is dominant —which is rare— all the descendants will have the same mutation, since this gene will necessarily be expressed.
A dominant allele is one whose presence produces the phenotypic expression of the characteristic it determines. When the mutation is dominant, it will always be expressed in the descendants.
Hungtinton's disease and achondroplasia are examples of mutations with an autosomal dominant inheritance pattern.

Which statement describes the movement of water when a cell shrinks and shrivels due to osmosis?
Water went into the cell because the concentration of water inside the cell was lower than the concentration outside the cell.
Water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell.
The cell membrane used energy to move water into the cell through passive transport.
The cell membrane used energy to move water out of the cell through passive transport.What area on the Iberian Peninsula maintained independence after the Reconquista?

Which of these events breaks down rocks into smaller pieces? (4 points) Sedimentation Deposition Weathering Erosion
Answer:
Weathering
Explanation:
Weathering is the breaking down or dissolving of rocks and minerals on Earth's surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

The photo shows a single-celled organism.
Which sentence best describes what this organism will look like at the end of
its growth period?
A. The same single cell, but larger
B. Two cells, but half the size
C. A small ball of identical cells
D. Three individual cells in a row
Answer:
B. Two cells, but half the size
Explanation:
Single-celled organisms, which are also referred to as unicellular organisms, usually have a growth mechanism or process known as binary fission.
Binary fission is a an asexual reproduction process that involves the division of a mature parent cell into two identical daughter cells of equal sizes that are almost half of their parents cell.
The sentence that best describes how the single-celled organisms shown in the picture above will look like at the end of the growth period is: "b. Two cells, but half the size"
